MACHINE FOR PRODUClNG PRINTING-*SURFACES.

SPECIFICATION forming part of Letters Patent No. 445,559, dated February 3, 1891.

Application filed June 25,1889. Serial No. 315,508. (No model.)

T0 (0% whom it may concern:

Be it known that we. FRANK AMOS JOHN- son and WALTER E. CRANE, citizens of the United States, and residents of the city of Minneapolis, county of Hennepin, State of Minnesota, have invented a certain new and useful Machine for the Production of Printing-Surfaces, of which the following is a specification.

The object of the machine is to produce a matrix in papier-mach or other suitable material from which to cast printing-plates by the stereotyping process, or in case intagliodies are used a casting mechanism might be substituted for the impression mechanism, producing logotypes, each representing a line of justified type, which can be used as ordinary type for printing, or to produce a printing-surface by stamping the letters into a plate or other material from which an impression may be taken directly, the letters standing out in relief asin an ordinary stereotype-plate, or being indented in the plate, as in copperplate printing, according as cameo or intaglio dies are used, or the machine may be used for surface-printing.

Our invention relates to that class of machines in which parallel lines of type or dies are moved in the direction of their length until the characters desired for a line of printed matter are brought into a transverse line.

In carrying out our invention we use fonts of disconnected dies movable longitudinally of suitable guides to assemble the selected characters into a transverse line and out of their originalpaths of motion for condensing into a compact or justified line, a line-holder adapted toreceive the selected dies at thetransverse line and permitthe necessary movements for condensation and distribution, and a diedistributer adapted to restore the entire line of selected dies simultaneously to their original positions in their respective fonts. The construction is such as to permit the ready correction of individual errors in the selection of dies before the impression is taken without disturbance of the other dies.

As the most common form of the machine is the one for the production of stereotype matrices, and as the other purposes for which the machine can be used are but modifications of this form, we will describe the machine as constructed for the production of nections by b and its powers, the condensing and impression mechanism by c and its powers, the movement mechanism for the type by (Z and its powers, the stop-setting mechanism by e and its powers, the matrix-material holder by it and its powers, the guiding and clamping bars by Z and its powers, the spaceindicator by n and its powers, the line register or indicator and proof-printing device by 0 and its powers, the type and collecting-bar by i and its powers, and the movement machinery, cams, shafts, levers, .&c., by c and a: and their powers.

Inorder that the detailed description may be. more easily understood, we will first outline the general workings of the machine.

o provide a series of parallel lines of disconnected type or diesas many as the maximum number-0f letters in any line to be printed. About forty-eight or fifty will ordinarily be found sufficient. lVe shall for convenience of reference call each ofthese lines oftype a font. Each font is mounted in suitable guides and contains one letter of each ofthe different characters that the machine will produce, also spaces and quads, and the characters are arranged in the same order, so that the fonts are duplicates of each 'other. As we have constructed the machine these fonts are contained in slots or channels in a horizontal table or bed. These channels may, however, be placed in a vertical or oblique position, if desired. At the commencement of the operation the fonts are all on onehalf of the table, as the left. Each font tends to move to the right by means of a cord and weight or other suitable means, but is prevented from so moving until the proper time by a pawl or dog in each of the channels. Now it is obvious thatby moving the fonts to the right differentdistances different letters will be brought to the center of the table. The key mechanism releases the fonts successively and allows them to move to the right different distances, according as different letters,- are struck. For instance, suppose we want to print the word and. The letter a is struck in the key-board and thefirst font of type (the one at the rear side of the machine) is released and allowed to move to the right until the letter a comes to the center of thetable. As the letter n is struck in the keyboard the second font is released and allowed'to move to the right until the letter n stands alongside of the letter a. The letter d would be chosen from the third font and brought in line with the letters a and n at the center of the table. In a similar manner enough characters are assemblcd in a transverse line at the center of the table to make a line of printed matter. This can be known by reference to a pointer or index, which registers the width of the letters as they are chosen on a suitable scale, the successive type or dies coming from successive fonts in the order of the choice of letters. This line of type which has been assembled at the center of the table is supported by a suitable holder and moved laterally, whereby the type are pressed close together or condensed to column width? The table is made to open at the center to allow of this lateral or transverse movement. The line of type or dies and the matrix material are forced together, forming a matrix. After the impression has been made the mechanism which supports the type returns each type to the font from which it was taken, the table is closed, and'all the fonts are forced back to the left half of the table, where they are held by the dogs alreadyv referred to until released again. \Vhile one line is being condensed and. the impression of the same is being made the stop mechanism, which arrests the movement of the fonts to the right, can be set or arranged for the next line. A duplieating or repeating device is added, by which the type, after making their first impression, are withdrawn, the paper-carriage moved sidewise the width of one column and the line impressed again, thus makinga duplicate matrix to be used in case of accident to the first matrix in casting, or it may be preserved to be used for subsequent use. 'A line registering or indicating device and proof making apparatus shows what letters have been selected and brought into the transverse line, so that any corrections or changes may be made in the line of letters selected before an impression is made of them, audit also prints each line on a suitable ribbon or sheet of paper, so the operator can see at any time all he has written, and this can be used as a proof-sheet for the matrix which has been made.' Instead of making the duplicate matrix, an impression can be taken direct from the condensed line of type to be nsed'as a proof-sheet, or the impression mechanism 'could be modified so that the type can be made to make one, two, or more matrices and on e, two, or more proof-sheets. In case a proof is taken direct from the type the proof-printingdevice referred to above can be dispensed with.

The machine embodies also numerous other devices of minor importance, which will be mentioned in the detailed description and pointed out in the claims.

The mainfrmne-The main frame consists of an open rectangular box a, supported by three standards, two near the center a and a suitable for receiving the principal movement machinery, and one a at the right-hand end. The rear central support a is placed a little distance from the frame to make room for the gear-wheels and is-joined to the main frame shown in Fig. 2.

by means of the projections (d. The keyboard is attached to the front strip a and the rear rod a, joining the central and right-hand standards. The impression-roll, paper-can riage, &c., are supported at the front by the standard a attached to the top of the main frame and at the rear by theupper end of the standard o Type and type-tabZe.-'lhe table or bed which support-s the type is in the upper part of the main frame and is made in two sections, one movable, composed of the bars I), and one stationary, with the frame composed of the bars I). These bars I) and b are thin strips of metal with broadened or widened bases placed side by side and fastened together, so that the upper surfaces or edges of the bars are a slight distance apart, leaving slots or channels between them, as shown in Figs. 5 and 18. In each of these channels is placed a font of the type or dies between a push-head d on the left and a stop head d at the right, as The bars I) are attached to two horizontally-movable cross-pieces b and I), the former resting on plates a on the illside of the main frame and the latter extending through slots (b 111 the front and rear sides of the frame. To the ends of the cross piece Z1 which projects through the slots to are attached the arms 1; and of front and rear toggle-joints, by means of which section b of the table is moved from right to left. At one on d bars Z) are fasten ed to the fixed cross piece I) and at the other to the right end of the main frame. The ends of the bars Z) enter slots in the ends of the bars Z2. as shown in Figs. 4, 6, and 7, and a portion of each is cut away on the under side to make room for the condensingoarriers, as will be explained in connection with the condensing apparatus. Each type consists of a body 25, (see Figs. 9 to 14, inclusive,) which rests on the bars I) orb,- as shown in Fig. 1 1, and of a projection or leg which extends down into the channel, by means of which it is guided. The upper left-hand portion of all the type in the oddnumbered fonts and the upper right-hand portion of all the type of the even-numbered fonts are cut away to make room for the guid ingand clamping bars, as will be explained farther on. The letter or character is out on the upper surface 25 as shown in "Fig. 12. One half of the leg i is made longer than the other half to enable the type to be better held while the line is being condensed and the impression taken, as will also be explained farther on. The bodies of the very thin type (is, PS, 830.) extend only half-way across the type, as shown in Fig. 11. Should two or more of these thin letters be chosen from adjacent fonts, this arrangement allows the parts of the type with the characters on to be pressed close together in the line when it is condensed. Each push-head (2 above referred to has a rib or widened partidat the bottom, which slides in the grooves If in the bars Z). (See Figs. 14, 15, and 16.)

Each stop-head d has a similar rib (i which slides in the grooves Z1 in the bars I). (See Figs. 4 and 17.)

Stop setting mechanism- The setting mechanism consists, chiefly, of stops for arresting the movement of the fonts to the right at the proper places, the stop-setting carriage, by means of which these stops are set in the channels successively, and the keyboard. 7

The settin.g-st0ps.'ll1e widened bases of the bars b (the portion of the bars at the bottom of the channels) contain vertical slots biin which are placed crank-shaped stops If, these stops being held in position by the adjacent bar. The upper part I) of these stops is normally contained in recesses 5 of the bars I). The lower part b extends down through slots b in a plate 1), Figs. 2, l8, and 22. By moving the projection 19 toward the front of the machine in the arc of V a circle the point Z2 is thrown into the typechannel.

Sop setting carriage-11m stop setting carriage is composed of the horizontal bar 6, attached to the slides c and 6 the former of which slides in a groove in the cross-piece and the latter in a groove in the standard a as shown in Fig. 2. On the under sides of the slides c and e are racks engaging two gear-wheels e and 6 which are rigid with the shaft c. A weight 6 attached to the cord 6", passing over the sheave e on the inside of the main frame, tends to move the carriage toward the front of the machine. (See Fig. 18.) A spring e is interposed bebetween the cord e and its attachment to the bar 6 to give the carriage a quick elastic movement when itis released. The carriage is preventedfroin moving by the escapementpawl e engaging the escapement-wheel e". The left-hand half of clutch 6 slides on the shaft 6 but is made to turn with it by means of a slot and pin orafeather. The escapementwheel 6 has forits axle the right half e of the clutch, which is on the end of shaft 6". It is made to turn forward with the clutch, and hence with the shaft 6 by the notches in the wheel 0 engaging pawls e the wheel e being rigid with a part of the clutch e )Vhen the carriage is moved backward, the pawls e slip in the notches of the wheel 6 without turning the escapement e. The slide e of the setting-carriage extends out in front of the machine and is turned to the right to form one support for the loop-shaped rod 6, the othersupport being a lug orbracket e attached to the main frame, through which the upper part of the rod e slides. The lower part of the rod c slides in a groovee in the part ciof the clutch. By turning the handle e to the left theloop-shaped rod 6 is rocked IIO and the clutch is opened and the carriage left.

free to move forward or backward. On the horizontal bar e are placed the springs 6 as shown in Figs. 2, 18, and 23. There are as many of these springs as there are stops in one channel and dies or characters in each font. Under each spring is a horizontal bar e whic'hrests in slots in the front and rear ofthe-main frame. Near each end of the bars 6 Wherethey pass through the main frame, are slanting-slots 6 through which and the partsoflthe frame between the slots are passed the'pins 6 which support the bars 0 so that as the bar is forced toward the operator it is raised at the same time. Each is moved forward by depressing its key 6 attached to the key-lever 6 which turns on the rod a as a fulcrum and moves in slots in the strip a In front of the main frame are bailsha'ped bars 01, (shown in Figs. 1, 18, and 21,) hinged at n tothe main frame and resting against the ends of the bars 6 In the right hand hinge of these bails is also fulcrumed the lever e which rests against the bars a, so as to be moved out by any ofthem. This leverworks the escapement pawl e by means of the connecting rod The spring e holds the lever to place against the bars a. As soon as the keys are released the springse tlirow'the bars 0 to the rear. The bar 6 to which springs e are attached, runs through the end of the main frame and has a ratchet-wheel e attached, by turning which the tension of all the springs can be changed. Aflstrip a of any suitable material, on top of the-slotted piece a affords a back stop or rest for. the key-levers.

Operation of the setting mech anism.-By depressing any of the keys the corresponding bar 6 israised and moved forward. The upward movement raises one of the springs e until it-stands directly behind the lower part b of the stops, at which time the bar 6' will have advanced forward enough so that the levere will drawthe endofthcescapement-pawl e outof its notch in the escapement-wheel 6, allowing it to turn one-half notch, a whole notch movement being prevented by the lower end of the pawl c. This allowsthe carriage to move forward, carrying with it the stop leaving the part b in the type-channel,as shown at the right in Fig. 18. As the key is released the bar 6 retreats, and as soonas the spring 6 is below the end of the stop the lever 6 will be retracted by spring c and will force the lower end of the pawl a out of its notch,allowing the wheel to turn one-half step more. By this movement of the carriage the inclined surface 6 of the bar e attached to the slide 6 of the carriage, strikes against .the left'end of the dog d of that channel, raising it, whereby the stop-head d is released and allows the font of type to move to the right until the stop-head is arrested by the stop which has just been set in the channel. Each key, its lever, the corresponding bar e and the corresponding transverse row of stops repreients a different letter or character, so that by striking any key the font of type which is-released will move to the right, leaving the corresponding die in the transverseline. The lower part 6 of the type-stops 6 projects down through slots 1) in the plate 6 as shown in Figs. 2 and 18. This plate isattached tothe cross-pieces Z1 which move in horizontal slots Fig. 1, in the front and rear sides of the main frame, said cross-pieces being. connected by swinging supports 6 at the rear and b" atthe front to the frame. The slots Z2 allow any of the pins 12 to be moved out into the type-channels. As the stop-setting carriage is moved back to the rear of the frame two ins e on thebare strike a ainst P o radius of one of the stops, so that as'the plate Z1 is moved to the rear it swingsin the arc of a similar circle with the stops. This allows the plate 11 to be made with smaller slots, and consequently greater strength, than if it did not swing through the proper arc, the slots being just large enough to allow the ends of the stops b to move in them freely. The

carriage is moved back farthef than is absolutely necessary in order to insure the plate I) and other parts having a full movement every time. The dotted lines in Fig-22 show position of the lever-armsb while this excessive motion is taking place. Asthe carriage returns to the first channel the springs b draw the plate back to its normal position, so that the stops can be set again. Should any of the stops be set in any of the channels at the left of the one previously used before the'fonts are return ed to their position on section b, the hinged part (Z of the stop-head d will rise, allowing it to pass over the stops without throwing'the stops out of position, and the stop-head will be engaged by the stop when the font again moves to the right. This is the device which allows the stops to be adjusted while the impression of the preceding line is being made, and also enables individual errors in the selection of dies to be corrected without disturbance of the other fonts. The pointer 0 Fig. 1, indicates on a suitable scale on the slide 6 of the setting-carriage the channel at which the stop-setting mechanism is situated. From the scale 0 of the lineregister can be determined the channel in which the error occurs. By moving the stopsetting carriage to the corresponding channel by aid of the pointer 0 the correct stop can be set by striking the proper key. If the new stop is at the right of the-one previously set, the font can be released by raising the hinged part d of the stop-head above referred to, when the type-weight will carry the font to the right until engaged by the new stop. If the new stop is at the left of the one previously set, the change can be made by simply pushing the font backin its channel until the hinged part 19 passes beyond thenew stop.

The collect/'ng-bav'.'ll1e fonts of type are forced back to their normal position by the collecting-bar 25 which is moved by means of the lever-arm t, to which it is attached by the cord t. (25 is represented in Fig. 3 by dotted lines.) to its position at the right end of the machine by the cord '6 and the weight 25 Condenshig or compacting and distributing mcchcmism.'lhe type-channels being the same distance apart, it follows that in the transverse line of type which is assembled at the center of the table each die occupies the same amount of space. An impression may be made of the line as it is thus assembled which would resemble the work of an ordinary type-writer, each letter occupying the same space and the ends of the lines uneven; but for ordinary printing, as in newspaper or book work, the dies in the line need to be condensed or forced together into a compact or justified line, and after impression to be distributed or returned to their respective fonts in time for use, if necessary, in the next succeeding line. To these ends we provide a line-bolder suitable to hold or support the transverse line of dies while they are being forced together and a die holder and distributer suitable for attaching to the individual dies and returning them to their respective fonts. lVhile the means we herewith describe we deem best adapted to these purposes, it is evident that other mechanical means might be substituted, and we do not wish to confine ourselves to the mechanism herein described. Extending across the ma chine from front to rear, immediately under the joining of the two sections h and b of the typc-table, is the impression-bed 0 This bed is supported by two legs 0 one at front and one at rear, which have slots cut in the bottom of them to set on the shaft '0 as shown in Fig. 2. These slots allow a slight upward movement of the bed, which is accomplished by means of the front and rear pairs of toggle joints t/ 'U 1: 1- The bed is moved to the left by front and rear pairs of toggle'joints '1' c c U the pins 0 at the front and c at the rear working in vertical slots 0 in the ends of the bed. Upon this bed, arranged in two rows, are the die carriers and distributors 0, there being one carrier for each font of type. The ends of the bars Z) and Z) are cut away, as shown in Fig. 4, leaving a recess b 011 each side of the type-channels, into which the upward-projecting parts 0 of the carrier 0 are placed, so that the slots c of the carriers are in coincidence with the type-channels, and as each font of type moves to the right the projections 25 of the type must pass through these carriers. The carriers are held in position by means of plates 0 which inelose the outer and upper sides, the inner and under sides resting against and on the bed 0 These carriers 0 have a movement from front to rear and returnduring the condensing of the dies for The collecting-bar is returned each line. They are returned exactly to place in coincidence with the type-chai'lnels by means of the wires or rods a one of which is fastened to each carrier 0 and extends through the intervening carriers to the front and rear of the machine, terminatingin a head 0 which abuts against the opposite sides of stationary plates c and c on one side and against opposite sides of movable gatheringplates 0 and c on the other. \Ve prefer to have the wires from one half of the carriers extend to the rear and from the other half to the front of the machine, though they may all extend to one side if deemed best. The movable plate 0 is attached to and made a part of the condensing-carriage c and the plate 0 is attached to condensing-rod c by means of its sleeve and is drawn back by the head 0" of the condensing-rod 0 and is pushed forward by the spring 0". After a line of type has been selected and assembled at the center of the table the projections 25' of the type in the line assembled will be found in the slots 0 of the carriers 0, the type of the odd-numbered fonts in the right-hand row and the type of the even-numbered fonts in the left-hand rowof carriers, the part i of the type coming directly over the part c of the bed 0 which separates the two rows of carriers. The whole bed is new raised, so that the projections of the type enter the space between the part of the bed 0 andthe upward projecting rib c of the plate 0 the corners of the projection 25 of the type being'cut away to insure the type always getting into their proper places. The guiding and clam ping bars Z and Z are dropped astride the line of type, as shown in Fig. 30. Sections I and b of the table are separated enough to make room for the die-holders or distrihitting-carriers c, with type t, to pass freely between the bars I) and b. This lateral movementof the line of type is effected by the condensing-rod c operated by the lever c and forces the selected characters together into column width. The head 0 of the condensing-rod strikes against the type. The plate 0 helps by gently pushing the carriers together, being made elastic by means of the spring c on the rod c Ordinarily the head 0 is pushed in only until it comes into the edge of the column, it being stopped by the arm 0 striking against a pin 0, the lever-arm "12 being made elastic. If the aggregate width of the lettersin the line of dies selected is less than the width of a column, the extra space may be taken up by flexible spaces, as a piece of rubber or a spring on the side of the spacingquads, so as to justifythe line of type. hen it is necessary for the plunger to enter farther to condense the partial line, as at the end of a paragraph, the arm 0 is raised before starting the machine in motion, so that the pin 0 will not be engaged. It is held up by the dog 0 until the head 0 gets beyond the edge of the column, when the downward projection of 0 strikes the inclined surface of the dog 0, releasing the bent lever 0 so that it will stop the carriage at the edge of thecolumn for the nextline. The type, after being pressed together, are impressed into the matrix material Z which is fastened to the under side of the holder 7.7 by means of the flanges Z3 or in any other suitable manner. This impression is given by further upward movement of the bed 0 The guiding and damping Z)(t)'s.Du1-ing the compacting of the dies and while returning to place they need to be prevented from tipping from right to left and'during the making of the impression to be rigidly held in alignment. For these purposes there are provided two bars or frames Z and Z, called clamping -bars. These are attached by means of slotted posts Z to the bed 0 making them move to the right or left, with the bed, and are attached to the main frame a by means of slots in the pieces (L13 and a which are secured to the top of frame a and which control the heights of the parts Z of the bars,

Zand Z. The slots a in pieces e and a are "1-shaped, and when the last downward movement of the bed 0 takes place the parts Z are pulled down in the vertical portion of the slots a by the posts Z the movement of Z in the slots of posts Z having all taken place during the rise of the bed to make impression and return, leaving Z at the upper end of said slots at the beginning of the final downward movement of the bed. During the final downward movement of the parts Z the parts Z and Z Fig. 29, act as fulerums on parts a and a, which are attached to co and a, by this means tipping up the bars Z and Z to a position shown by the dotted lines in Fig. 80 for the purpose of clearing the type during the rearrangement for another line. With the first upward movement of the bed the arms Z rise, allowing the bars Zand Z to turn on e and a as fulcrums, dropping the bars Zand Z on the line of type, as shown in Fig. 30. Vhen the bed 0 is raised to its highest position to make the impression, the clamping-bars are brought up to a horizontal position, as shown by the dotted lines in Fig. 30, holding the type tightly; but when the bed is partially lowered the type and bars are in the position indicated by full lines, leaving the type free to move between the bars and guiding them for the condensing and return movement. As the impression-bed and section Z) are moved to the left, the parts Z slide in the horizontal parts of the slots a Attached to and rigid with the bars Z and Z are the projections Z", connected together by the spring Z for the purpose of forcing downthe bars Zand Z and the type when the downward movement of the bed occurs.

In its normal position this check-bar is held up by the lips Z resting on the bar Z. When the bar Z is' lowered, the check-bar 2 descends with it between the line of type selected and the portions of the fonts remaining on section Z), and as section Z) is moved to the left this cheek-bar carries the portions of the fonts with it, resisting and overcoming the force of the weights (Z hen the move ment to the left takes place, the cheek-bar being moved farther than the clamping-bars, the lips Z are moved off the bar Z,so that the cheek-bar will not be raised by Z when the bed and clamping-bars are raised to make the impression; also, the ends Z of the bar Fare drawn under the plates a as a further means of security. After theimpressi'on of theline has been made the return movement of the condensing-carriage and plunger sets each of the carriers 0 with its type opposite its typechannel, as already explained. As sections Z) and Z) come together, the tongue I), having wedge-shaped ends b pass between the carriers, as shown in Fig. '7, and enter vertical slots Z) in the bars Z). The wedge-shaped plates b of the bars Z) pass between the type and enter the horizontal slots Z9 in the bars Z). These centering devices insure the carriers and type getting back to their proper places in line with the type-channels.

Impressionwdl and dupZicating apparatus.The impression-roll turns in suitable bearings in the standards (0 and c On this roll Zr; is an impression-sleeve Zr, to which is attached a pinion Z0 Fig. 27%, to move the matrix-material holder k by means of the segmental rack Zn.

This acts on the connecting-rod 7e which is attached to the collared sleeve 76 or the brace 75 and draws the impression-sleeve toward the rear of the machine. By the no ward movement of the sleeve 73 the pawl k is withdrawn from the pin it, and the pin 7& being then at the top will be engaged by it in its next downward movement, when the lever 73 will be reversed and the impression-sleeve thrown back to its original position. In this manner one line is printed in the original column and then in the duplicate. The next line is printed first in the duplicate column and then in the original, and so on alternately. The lever 70 may be providedwith holes or a slot to make provision for differentwidth columns. This duplicating or repeating device is not an essential part of our machine. Instead of making the second ma trix, paper may be substituted for the matrix material, an inked ribbon or carbon paper interposed, and a proof taken direct from the line of type.

Space-indicator.-As before stated, the dies are all multiples of some unit. lVe have provided an indicator which registers the width of each die as it isbroughtinto thetransverse line. The object of the indicator is to exhibit to the operator the aggregate width of dies assent bled and also the amount of space remaining in the line, and also to aid in tabular work. I-Iingedat n and hanging in front of. the bars 6 are the swinging bars 12-, as shown in Figs. 1, 18, and 21. These bars have projections M, which rest against the bars 6 Each bar at can thus be made to represent a certain number of units, the projections n from that bar being so located as to rest against all the bars 6 which representletters of that width or a number of units, so that when any twounit letter is struck one of the bars 72. will be forced to the front and when any threeunit letter is struck another of the bars it will be forced to the front, and so on. In the drawings we have shown but two of the bars n. About five or six are ordinarily required. As the bars a are moved forward theinclined surface a of the projection M, as shown in Fig. 30%, strikes against the arm n and forces it to the right. The pawl 01, attached to the lover-arm or", moves the segmental ratchet 71 which is attached to the pointer a moving over a graduated scale n. The arm a extends up through a slot in the support 71 and is drawn back to the left by the spring am. A set of stationary pawls n prevents the pointer from being drawn back. The pawls a and n maybe single; but we prefer differential pawls. It will be noticed by referring to Fig. 30% that the inclined surface a will not strike the bar a until it has moved about one-third its distance, and that the full movement of n is effected by the secondthird movement of 72*. So by a twothirds stroke of the key one is sure of the full count of the register, while a mere touch or accidental stroke up to one-third of a full stroke will not be registered at all. This also allows one key to be partially depressed before the previous one has fully returned to place. The pointer a will show at all times the aggregate width of the (lies which have been selected. ()n the under side of support 77. is attached the support 11. for theangularpiece n carryin the. bell-hammer 72 which is made to strike against the bell n when the dog n leaves the piece 77. The bell is made to ring when the pointer lacks several units of enough to fill up the line. The pendent dog at allows the pointer to return without ringing the bell. The piece n is fulcrumerl on the same pin as the pawl a and has a pin 11" extending forward under the pawls. A piece 17. is similarly fixed with reference to the pawl it Thebar n is pivoted to piece it and has a slot in it through which projects the pin from the piece ii The slot allows piece 12?, together with the baro'fi, to move to the right. By drawing the rod n to the right the pins n and n are raised, releasing the pawls n and n from the segmental ratchet 17. when the weight n will return the pointer n to the zero-mark. The rod n is drawn to the right by the inclined surface of slide 8 striking against the lever 01 which is hinged at n to the main frame. (See Fig. 21.)

Linereg-ister and proof-printing mechanism.ln order that the operator may know just what letters have been selected and assembled under the impression-roll and thus be able to correct any mistakes or make any changes before the impression is made, aline register or indicating apparatus is provided]. As a letter is struck in the key-board a corresponding letter appears in the horizontal slot above the graduated scale 0, which indicates the channels from which the letters were taken, so that by the aid of the pointer 0 ona suitable scale on the slide 6 of the setting-carriage the setting mechanism may be moved to the proper channel an d the corrections made, as already stated. At the same time that the line of type is being impressed into the matrix material the paper-holder 0 moves to the right and receives an impression of the line. The operator thus has before him a copy of all he has written, and as soon as a column of the matrix has been made a proof-sheet is ready for the proof-reader. To these ends a series of parallel bars 0 are provided, having grooves o in their sides. These bars are made to slide on the wires 0 in the frame 0 The frame 0 is attached to the bed 0 which passes under the bars 1), and is securely fastened to these bars,so as to move with them. The bed 0 and the frame 0 are placed at-an angle with the main frame, so that the proof-sheet and line in the slot are nearly squarely facing the operator. The bar at the left is attached to the weight (Z of the first channel by means of a braced arm The bar next to the right is attached in like manner to the weightof the second channel, and so on, there being as many bars as typechannels. Each bar 0 has printed on its front surface with good clear type all theletters or characters the machine will produce. As the first key is struck (suppose,'for illustration, it is the letter m) the first font is released and moved to the right until the letter in is under the impression-roll, as already explained. The downward movement of the weight (17, which moves this font, carries with it the first bar 0 and leaves theletter min plain sightin the horizontal slot 0.

, In this manner as fast as the dies are assembled under theimpression-roll corresponding letters appear in the slot 0 The reverse surface or rear side of the bars 0 is provided with raised type corresponding to the char acters printed on the face of the bar. A sliding table 0", Fig. 31, carrying the paperholder, a roll of paper, impression mechanism, &c., is fastened to an upright piece 0 by means of two strips 0' and 0 extend across the whole length of the table 0*. 0 is attached to the plate 0 The paperholder 0 is held in position by means of the two braces o The two braces 0 extend below the table 0 and afford bearings for the shaft of the feed-roll o and the spring-plate 0 The impression-bar 0 swings from the axes of the roll 0, and one.end has attached to it the pawl 0 which turns the feed-roll by means of the ratchet-wheel 0 The paper passes from the magazine-roll 0 through between the feed-roll 0 and the 'metal plate 0 upward past the impressionbar 0 and is fastened under the plate 0 which is drawn up the inclined surface of the holder 0 by the cord 0 to which is attached a weight. (Not shown.) By the downward movement of. the arm '0", Fig. 1, the collar c attached to the rod e strikes against'the lever 0 hinged at o to the main frame, overcoming'the force of the spring 0 which holds it up and brings it down on the toggle-joint o 0 on top of the table 0" and drives the impression-bar o out, impressing the paper onto the line opposite the slot 0 As the bars descend they pass over an inked pad or surface-0, extending across the rear of the frame 0 On the edge of impression-bar o is a strip of rubber or other flexible substance, which enables a good clear impression to be taken from bars having hard-surface type. Rubber type maybe substituted for metallic on the bars. An inked ribbon may be interposed-between the type and the paper and an impression obtained from it, thus doing away with the inked surface 0 In this manner two or more rolls or sheets of paper may be run through with carbon-paper between them, producing duplicate copies of the proofsheets, if required. The table 0" is moved to the right to allow the impression of the line onv the proof-sheet, as follows: The rod '0 These strips Fig. 1, has a branch which passes between twoguideposts r on top of the main frame, Fig. 31, and enters the-sloto in" the leverarm 0 Fig. 34. As 'the rod "0 is drawn downward the bar 0 is drawn to the right until the lever 0 reaches a horizontal position. Two gear-wheels o and 0 0 being slightly larger than 0 are fastened together and placed as shown in Fig. 0 moves in a rack on o, and 0 engages the movable rack 0 movable top 0 by means of a brace 0 Now itis evident that by drawing the movable rack 0 one inch to the right the top 0 and all parts connected with it will be moved several inches to the right. The slot 0 allows of a further downward movement of the rod 15, which is necessary to give the impression without moving 0. 0 is returned by a cord and weight. (Not shown.)

Mechanical movements. All the movements connected with the machine are automatic except the operating of the bank of keys to select the desired dies and the starting-key to set the machinein motion. These movements are all generated primarily from the compound cam-wheeler. Passing through the central supports a and a and having suitable bearings therein are the shafts as, 00 n, "0 and v. The shaft 00 is the powershaft, and is driven continuously by any suitable motor acting on the pulley 00 or in any other desired manner. The shaft or is the movement-shaft and produces allthe necessary movements by one revolution, after which it is stopped automatically.

The movements generated by one revolution are as follows:

First. The wheel :0 is raised slightly by cam-surface 00 This raises the bed slightly by means of the front and rear toggle-joints c '0 15, so that the type rest in the die-holders and distributers and are slightly raised, so as to clear the table. The same upward movement of the bed lowers the check-bar and clamping-bars, as already explained.

Second. The wheel 00 is forced outward by the cam-surface 00- tipping the shaft n which runs to the rear of the machine and has attached wit the lever o to the end of which is attached the cord 6 which passes over the sheave e on the rear of the main frame and is attached to the setting-carriage c, by means of which the carriage is returned quickly to its position at the first channel. This move ment of the carriage permits the space-indicator to return to its first or zero position, as already explained, and also returns the setting-stops.

, Third. The cam-surface as next strikes the roller 00 and forces to the right the lever o which is connected to the toggle-joints c c and o and n the latter at therear of the machine. The arms 1? and '0 are attached rigidly to the same shaft, and the lower part of lever v is connected to o by bar 21 The pin 0 extends through a slot inthe main The two wheels are fastened to the frame, working in a vertical slot in the bed 0 The parts 1; and o are attached to cross-piece h of section b, and thus these toggles move the bed and section b to the left.

Fourth. The face-cams m and an, acting simultaneously on the two rolls x and 02 work the lever c which controls the con- (lensing-carriage. The lever e is added to keep links 2: and r parallel with the shaft or. The lever '22 and parallel lever 1: have their fulcrums in the plate d Fifth. Cam-surface of strikes the roll .90 straightening out the toggle-joint e and e, and a corresponding one at the rear of the machine 11 and c worked by the shaft o, raising the bed and impressing the dies into the matrix material.

Sixth. Canrsurface at" strikes roll 01;, drawing down the lever-arm c and rod U5, changing the column and operating the lin e register and proof-printing device.

Seventh. Cam-surface 00 strikes the roll 03 and makes the second impression. .1 extends across only one-half the surface of 00, so that it does not strike the rolls or, a", w, and an.

Eighth. Cam-surface 00" strikes roll 00, throwing back the lever o and closing the table, being the reverse of the third movement.

.Ninth. The cam-surface c strikes the roll a, drawing down the lever 12 which moves the collecting-bar to the left, returning all the fonts to section b. The collecting-bar returns by a weight i as soon as the cam allows a to retreat.

Tenth. Roll drops from cam surface x to the normal surface of the cam, producing a movement the reverse of the first, lowering the bed and raising the clamping and cheek bars. On the shaft 00 is the gear x and pivoted in this gear is the lever m Attached loosely to the shaft at by means of the sleeve x is the shipper-plate which controls the half-clutch 0a, which is attached to the shaft a? by means of a feather, which allows it to slip freely longitudinally, and thus to engage the similar half-clutch on pinion ar which is loose on shaft .70 and is revolved only when engaged by clutch so". The shipper-plate is pressed toward the gear .90 by a spring a. Pivoted in standard a is the gravity-stop 5 supported and controlled at its front end by the toggle-joint composed of parts a' and 03 The lower part of is firmly attached to shaft of, which terminates in a crank which is connected by rod .70 to a starting key-lever. As shown in Fig. 3,1he mechanism is thrown out of gear, and the shaft 00 would not revolve if as were started; but when the starting-key is depressed lever as is deprived of its support, when the spring is immediately overcome by the stiffer spring 00" moving the shipper-plate forward, causing clutches c3 and a to engage, and thereby starting gear .05 and cam-wheel By means of a ball on the end of the lever 120 it is returned to its original position, as shown, as soon as the lever 00 passes below it, and is in position to intercept 5 when it has made one revolution and stop the mechanism by 00 overcoming the spring a), and thus opening the clutches.

We have shown and described our machine as constructed for the production of matrices; but, as is hereinbefore stated, the principle of the invention, so far as relates to the assembling and distributing of dies, is equally applicable to the production of raised impressions or to the production of logotypes or lines of stereotype-plate, and all terms herein used-such as dies, impressions, and impression material, are used in a sense broad enough to include all these purposes.
